It is not surprising that we are the leading experts in the energy market.

At a glance

The strategic backbone of the RWE Group

There is one goal that we pursue consistently: to provide the best possible consultancy service for the RWE Group and its partner companies on the crucial questions that the energy market involves, whether these be strategic issues or economic ones. Our credo is not to make empty statements – we always think ahead and then take the necessary action. This is how we define our own standards for ourselves as one of the largest in-house management consultancy services in Germany.

Our field of activity is energy – in all of its facets. Consulting projects and issues are spread throughout the entire value-added chain in the energy industry. Our expertise in the management of energy is the basis for our consulting activities in the RWE Group.

With over 140 people working in our locations in Essen, Berlin, Frankfurt, London/Swindon, Den Bosch, Prague and Dubai, we continue to enhance the progress of the Group and further its development on an international level.

The quantum perspective

The expectations that we have for our own work methods are clearly defined: a deep thematic understanding of the RWE Group and the industry are our most significant distinguishing features. The combination of management consulting and our situation as an integrated part of the corporate structure of RWE makes RWE Consulting unique – consulting with energy. This is clearly illustrated by our numerous projects in Germany and other countries. Our work always centres on close cooperation with our customers while maintaining a results-oriented approach.

      Energy experts

      When it comes to energy expertise, we are second to none. Our consultants know what they’re talking about – whether the subject is energy management in the fields of gas or electricity, an issue in energy politics or an aspect of the current discussion on the transformation of the German energy industry. They have the crucial specialist knowledge that allows them to be familiar with the energy market or the process of grid development as well as the backgrounds behind gas procurement, gas transportation or gas storage.

      Only those in the know can take new directions

      Our consultants know which management tools are most appropriate for each specific issue in energy management and apply their specialist knowledge with a broadminded approach and critical judgement in order to maximise the advantages for the customer.

      Demonstrated energy expertise for sustainable results

      Anyone who wants to provide effective consulting service for one of the largest energy providers in Europe and the largest electricity producer in Germany needs to be well versed in the business of generation, transport, sales and marketing of electricity and gas. We have the integrated know-how to face up to the task of continually expanding the position of the RWE Group. The challenges we face are diverse, and our team of consultants at RWE Consulting combines the necessary diversity of expertise. RWE continuously develops new, innovative technologies to use energy more efficiently, cost-effectively and ecologically. Changes in generation capacity, changes in the power plant portfolio or changes due to renewable energies – we are familiar with all of them. We believe that this is the only way for us to genuinely fulfil our customers’ expectations – and achieve sustainable added value.

        An international outlook defines our daily business. Together with RWE, we are on the path towards internationalisation. Since our establishment in 1981, our business has extended beyond borders.


        In-house consulting – a wide field

        For energy leaders, there is no such thing as a typical consulting project. No two projects are alike and each project has its own specific challenges. However, there are designated project fields that we continue to work on with our customers. These are just as diverse as the issues faced by the RWE Group itself and cover virtually all of the facets of the classical management consulting or strategy consulting. These range from process optimisation, change and restructuring to internal benchmarking and strategy development or lean management.


        The European Union has stipulated that all member countries implement smart metering in order to improve transparency and increase energy efficiency in the long term. Unlike existing mechanical meters, smart meters are electronic devices. The data collected is passed on to the electricity customers via an interface. This means that customers can see how much electricity they consume by looking at their daily or weekly statistics. The aim of this transparency is for customers to be able to get a feeling for how much they can save by switching off certain devices, for example.

        As an internal management consultancy for the RWE Group, RWE Consulting functions as an interface in the Smart Meter rollout project. The consultants will sit down with subject matter experts within the Group in order to answer key questions, develop approaches and discuss strategic directions with management.

        We will be analysing how the project and the new business can be integrated into the existing organisation. We will also be looking at what it will mean for the organisation, staff competencies, processes, data protection and security, as well as how it will change corporate culture.

        RWE Consulting has also been tasked with the project management. The consultants will keep a close watch on the schedule to ensure that the Smart Meters will be able to be rolled out across the country as planned. They will be responsible for pilot projects and training design, and will identify new staffing needs and the relevant competencies required. The consultants will assist with efficient approaches and the selection of suitable partners, identify the needs in terms of meters and scope the functionality requirements.

          as consultants, we must also approach the “how”


          Considering the difficult circumstances with which the Group is now faced, RWE is planning to provide the staff and management with a means of successfully overcoming the large and complex transformation that is taking place within the Group. To do so, we are linking the question of “what we need to do” with the question of “how we need to do it”. A team of consultants from RWE Consulting is already actively tackling this task and leading the way in the area of change!

          “The principle that permanent improvement as well as change needs to be practised must become a part of the DNA of our Group. Change is not even something that can be smoothly regulated. However, it needs to be introduced through management and also modelled by them. This is why our efforts focus so specifically on the development of executive managers and providing support of the teams. We would like to take a different approach and find a different solution to our challenges – to create sustainable changes that are immediately tangible and observable,” says RWE Consulting programme manager Andrea Kahlenberg to describe the objectives of the programme.

          A concrete example of change is the formation of the RWE corporate story, which consultants at RWE Consulting on the Change team worked on, amongst others. This process involved new methods: online chats (Synthetron sessions) were used for concentrated discussions with over 300 executive managers regarding the advantages and disadvantages of possible future visions. Every Group company was directly involved – after all, the big picture needed to be broken down for each company eventually.

          With the support of RWE Consulting, the RWE Group has started out on this long journey of change. These far-reaching behaviour changes take time, but they are the basis for the transformation of RWE’s role in the energy industry.

            putting the focus on the customer

            Customer transformation programme

            “The objective of the customer transformation programme is to put the focus on the customer. We would like to orient our entire organisation towards this goal. Anyone is welcome to join me on this journey. It is the only way that we can remain competitive.” This is the clear goal that was set out by the CEO of the UK sales company nPower, Paul Massara, at the beginning of 2013.

            RWE Consulting has accompanied nPower on this journey and worked together with nPower to implement measures aimed at improving customer orientation while achieving significant cost reductions at the same time. The “Customer Transformation Journey” programme included over 300 improvement measures. The work package “End-to-end Processes” was just one of the three that consultants from RWE Consulting put together to assist nPower. This work package consisted of six main processes (“customer journeys”) that were analysed from start to finish in order to simplify and improve them.

            Each process was considered from the viewpoint of the customer. The processes were deliberately given titles that reflected the customer’s perspective: “I move, I pay, 
            I enquire, I join, I leave, and my terms change.”

            The work package “Leadership & Direction” deals with processes of change amongst the management. Are the performance indicators in the company compatible? Is the existing structure of meetings practical? Is the communication from management clear enough? The third component of the programme aims at “Operational Excellence“, the implementation of a completely new working method on an operational level. In this part of the programme, there are great opportunities for demonstrating how each employee can contribute in terms of value. Moreover, it highlights how each employee can reaffirm his or her commitment to the goal every day: 
            by putting the focus on the customer.

              Creating the grid business of the future


              For the RWE Group, an increasingly important task for the future is the creation of small, flexible business units, known as speedboats, which can develop new, innovative products within the context of the transformation of the energy industry. But what kind of support processes should be in place for these small business units? To answer this very question, RWE Consulting has developed a prototype for this purpose as one of its projects. As a small unit within the Group, RWE Consulting is responsible for looking into outsourcing in specific areas and implementing it, with the objective of gathering experience to apply to this approach. The project team began by focussing on the redefinition of internal service processes. Next, these processes were advertised. As a result, it was decided that we should cooperate with an external service provider from now on. The service provider will take over the processes in finance, purchasing and HR for RWE Consulting and future speedboats. The processes have been deliberately streamlined. The project team has therefore achieved much more than simple process optimisations. Using a greenfield approach, the team did not just analyse the existing organisational structure, but considered the ideal format for the structure. Basically, they scrutinised all of the components that constitute a process. And then reduced them to what was needed.
